VENTILA'IOR.

Specification of Letters Patent.

' Patented Dec. 11, 1917.

Application filed J une 28, 1916. Serial No. 106,324.

To all whom it may concern:

Be it known that I, FREDERICK J, AoKER, Jr. a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Ventilators, of which the'following is a specification.

My invention consists of an improved form of ventilator, and is particularly serviceable for use in windows and doors. One object of my invention is to provide a ventilater which may be quickly and easily attached to and removed from a window or door or which may be included with a framed screen for use in windows, doors, etc.

Another object is to so construct my improved ventilator that it may be readily closed or opened to different extents.

A further object is to provide my ventilator with means which act both in the capacity of fastening devices for the ventilator, and also as means to facilitate the removal of the ventilator from a window or frame of any description.

These objects, and other advantageous ends which will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawings in which-- Figure 1 is a perspective view of my in vention attached to a framed screen.

Fig. 2 is a section on the line (re-w of Fig. 1.

Fig. 3 is a section on the line b?) 'of Fig. 2 on an enlarged scale showing certain of the central portion broken out, and

Fig. 4 is a perspective view of my invention as it may be attached to an ordinary window.

Referring to the drawing, 1 is a pivoted frame which has a covering 2 preferably of light colored transparent cloth which will permit air to pass therethrough, but which will prevent dust or dirt from passing therethrough.

Longitudinally extending angular bars 4:, have their legs 5 pivotally connected at their lower .ends with the lower portion of the frame 1 by means of pivot screws'or bolts'fi. Each of the legs 5 also has secured thereto on its outer surface, one edge of a substantially triangular flexible fabric section 7. The opposite edge is secured or formed integral with the cover 2, said cover being may be readily backed by a strip 8 of wood'or other material to securely fasten it and the triangular sections 7 to the frame.

The sections 7 are also preferably connected to the opposite portions 9 of the frame 1, and'the upper edge of each of the sections 7 is preferably reinforced by a strip of tough durablematerial 10.

The legs 11 of the angular bars 4 have T-shaped openings 12 and flaps 13 which are cut and pressed therefrom. These flaps 13 are preferably shaped as shown in Fig. 1 to provide relatively narrow necks 14 and enlarged heads 15 which serve as cleats for an adjusting cord as will hereinafter be described.

The legs 5 of the angular bars a are de signed to fit against the inner surfaces of a Window frame, or as shown in Figs. 1 to 3 inclusive, against the surfaces 16 of the screened frame 17 The legs 11 of the bars 4 are oppositely disposed as clearly shown in Fig. 3, and the legs 5 and 11 of each of the bars a extend substantially at right angles to each other in order to envelop or cover the corner edges 22 of the frame 17.

The lower ends 23 of the legs 5 of the bars 4 are designed to engage the upper surface 24: of the frame 17 to vertically support the weight of the ventilator, the screw eyes 18 acting to prevent the bars t from falling away from the surface 21.

The flaps 13 are positioned adjacent the T-shaped opening 12, so that when attaching the ventilator to the frame 1?, the flaps 13 may be easily grasped between the thumb and first finger of each hand, so that the parts may be directed within the frame .17 and over the heads of the screw eyes 18. After this position is secured, the bars 4: moved downwardly without releasing the grip on the flaps 13 until the end 23 engages the surface 24: when the ventilator will be in place.

As ameans for securing and moving the frame 1 into difierent pivotal positions, I provide a cord 25 having one end secured to a staple 26 which extends from the face 27 of the frame 1. This staple 26 is of such size and so located with respect to the pivot bolts 6, thatwhen the frame 1 is in its closed position between. the legs 5 of the bars 4, the staple 26 will freely pass over the head of one screw eye 18.

The cord 25 extends through said head of the latter mentioned screw eye 18, and has a loop 28 which may be fastened onto an additional flap 29 located adjacent the lower end of one of the bars 4.

If it is desired to entirely close the ventilator, the loop 28 is pulled downwardly which draws the cord through the head of said screw eye 18, and also moves the frame 1 into its closed position. The loop 28 may then be placed over the flap 29, thus securing the frame 1 in a closed position, or said head 18 may be turned a quarter of a turn, and thereby lock the staple 26 to it.

If it is desired to move the frame 1 into an intermediate pivotal position, the cord may be wrapped about the flaps 13 and thereby secure it in place.

The frame 17 is provided with the screen 30, and this screen may be secured to the frame in any manner so as not to interfere with the provision of the corners 22 of the frame 17.

In Fig. 4, I have shown my invention attached to an ordinary window, in which case the screw eyes 18 are secured directly to the outer portions of the window frame, and the ledge formed by the window frame acts as a support for the lower ends of the angular bars of my invention.

. While I have described my invention as being adapted to a screened frame and to a window frame, it will be noted that it may be readily inserted within any frame providing a support for the bars 4.-

While I'have described my invention as taking a particular'form, it w1llbe understood that the various parts of my invensaid end portions of the ventilator tion may be changed without departing from the spirit thereof, and hence I do not limit myself to the precise construction set forth, but consider that I am at liberty to make such changes and alterations as fairly come within the scope of the appended claim.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

The combination with a frame support having members projecting therefrom adjacent itsedges, a ventilator having a front section and flexible end sections connected to opposite ends of said front section, vertically extending angle bars connected to an having openings in the legs thereof which bear against the outer surfaces of said frame, said bars having their inner angularly disposed surfaces shaped to embrace the projecting corner edge portions of opposite sides of said frame and to permit said members to extend through said openings, and means for pivotally connecting the ends of said front section to the legs of the angle bars which are adjacent inner opposite surfaces of said frame, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
